Advantech Introduces 12-Channel Sink and Source Type Digital Output Modules

Cincinnati, Ohio (August 18, 2004) - Advantech Corporation, Industrial Automation Group released today the 12-channel ADAM-4056S sink type and the ADAM-4056SO source type isolated digital output modules. These two modules support higher maximum load than any of the other ADAM-4000 I/O modules, and feature a communication watchdog, fail safe outputs, as well as support for the Modbus RTU protocol.

A maximum 200mA load of the ADAM-4056S digital output is suitable for use with versatile devices having sink type digital inputs. The 1 A per channel of the ADAM-4056SO digital output signal is useful for applications such as solenoid valve control in chemical plants.

Both ADAM-4056S and ADAM-4056SO are equipped with communication and system watchdogs as well as a fail safe function that resets the outputs to predefined values. The ADAM-4056SO also provides overload protection when the current draw exceeds 1 A. With these built-in protection functions, the ADAM-4056S and ADAM-4056SO ensure dependable operations.

Advantech also provides the ADAM-6052 for applications that require Ethernet-based source type digital I/O modules with support for the Modbus/TCP protocol. The ADAM-6052 is a 16-channel source type digital I/O module with 100Base-T Ethernet interface.

Advantech has in stock and ready for purchase the ADAM-5056S, ADAM-5056SO and ADAM-6052 modules. For more information visit or call 877-294-8989.
